1 My invention relates to what I call a burner gun as a short namedescribing mechanisms and methods of operation which isadaptable to beused in a variety of ways for acting upon various materials forproducing products which result from mixing, heating and smelting anumber of difierent materials for qualities of various materials.

I succeed in doing a variety of work withmy mechanism herein shown anddescribed without material changes of the mechanisms which I employ.

As a preliminary explanation of my invention by its use I may takepowdered or granulated iron,

ore with which there has been mechanically mixed powdered coke or coal,and pass this materialthrough my mechanisms wherein there takes placecombustions of fuel in liquid or gaseous producing special 2 Claims.(Cl. 263- 29) form into a stream of the above mentioned powderedmaterial carried by a blast of air into a furnace chamber whereby therethen takes place the result of progressively smelting the' iron or otherore to form products of metal or metal compounds somewhat analogous tothe. blast furnace used for making pig iron fromv iron ore.

My invention may be used for making numerous, different products bymixing and bringing to,-, gether a variety of different materials whichwhen mixed together in special proportions and in the presence of heat,chemical reactions will take place whereby there is produced specialdesired products of metallic and other compounds.

An object of my invention is to provide mecha-- nical means for mixingsteam, air or gas of any composition along with liquid or gaseous fuelsinto a combustion chamber and simultaneously therewith provide means formixing and entering into and discharging from the said combustionchamber various types of materials in which chemical reaction may takeplace through heat produced in the said combustion chamber.

A further object of my invention is to provide in a single unitmechanical constructions which will feed a plurality of materials into aplurality of separated mixingchambers wherein mixing" will take place,and then discharge those mix- Figure 2 is a top plan sectional view, ona smaller scale than that of figure one, on line 22. of figure 1 lookingin the direction of the arrows l-l.

Figure 3 is an elevational view of a modified 1 construction of mymechanisms.

Figure 4 is a sectional view on line 44 of Figure 1.

Figure 5 is a. sectional View on line 5-5 of Figure 1.

In the drawings 2 indicates a combustion chamber lined with suitablematerial of vitrified character adapted to support any heated materialswhich may be entered therein The combustion chamber 2 opens into a largevolume settlement chamber3 which is also lined in a similar manner totlhat of chamber 2. This lining as to both of the chambers 2 and 3 isindicated by 4;

In the chamber 3 there is provided a vertical cylindrical or other"shaped discharge tube 5 which is closed at its bottom end and isprovided with apertures 6 into the interiorof this discharge tube 5.,The top of the tube 5 is covered over by a plate 1 and is provided witha discharge pipe 8 extending to any suitable means for exhausting gasesfrom the tube 5.

The bottom of the settlement chamber 3 is provided with open spacesbetween what may be termed spokes 9, see Figure 2, of a wheel con- 4struction, the hub of which supports the closed" tures simultaneouslyinto a combustion chamber, wheregpnder the influence of heat chemicals,

reactions will take place, and do this without necessarilychanging theconstructions of the f mechanicahpartfs of my mechanisms.

Reference will be had to the accompanying drawings in which apparatus.

Figure "'l' is a sectional elevation through my'l' end of the tube 5.Below the bottom of the spokes 9 there is the catch basin wall In set atan incline, into which there falls by gravity the materials that mayresult from the reaction which takes place in the combustion chamber 2.On its side this catch basin I0 is provided with asliding vertical gateblock I! whereby access may be bad to the catch basin I 0 by thevopening ofthegatell.

The depth of the settlement chamber 3 below the combustion chamber 2 maybe of any desired depth as to the ratio of distances for largeinstallations of my apparatus. That distance may sometimes be requiredto be anywhere from ten to fifty feet deep below the apertures 6 in thetube 5. v

The-combustion chamber 2 may, as desired, be provided with vent openingsl2, see Figure 1, which maybe closed by revolving gate l3 as de: siredhaving the handle knob I4.

The materials to be acted upon in the combustion chamber 2.

position in any suitable manner and for certain uses of my apparatus maybe disconnected entirely from the combustion chamber 2 and may then beused as a unit or gun by itself. 1 This unit or gun may at times, ifdesired, be small enough to be held in the hand of an operator and usedas a gun or a torch when this unit is suitably provided with means fordelivering to it the materials to be acted upon. Or the tube may be madein dimensions and capacity for acting as a com-'- mercial blast furnace,as it were.

This tube l5 at its right end is closed. by a plate I6, and on theinside of the tube I5 there is mounted a central worm supporting tube H.The left end of the tube I1 is indicated b I8 and is supported at thisend into the tube l5 by a spoke ring l9. In the tube I! at its left endthere is' mounted a spoke ring the hub of which acts as a bearing for aworm shaft 2| on which is mounted worm blade 22. The worm shaft 2| is atube and is mounted in a gland bearing 23 in the right end of the wormsupporting .tube ll. The said worm shaft 2| extends to the right of thebearing 23 and is mounted insuitable'bearings 24 in a frame block 25.

- The frame block 25 is provided with suitable bearings for supportingan electric motor 26 or other suitable source of power which is gearedto actuate a gear pinion 21 and the latter geared to drive a gear 28 onthe aforementioned Worm shaft 2|. The worm shaft 2|, as before stated,is a tube and it terminates at its right end at 29 where it is mountedinto a gland bearing 36 and in this gland 30 the tube 2| telescopes intoa fixed pipe 3| mounted in the aforesaid frame block 25. The valve 32controls the flow through the pipe 3 l.

Into the right end of the worm supporting tube N there enters from itstop side a pipe 33 from a hopper 34. A conveyor belt 35 passes over aroller 36 suitably mounted and supported whereby materials which may bedeposited on the belt 35 may be discharged from the belt 35 into thehopper 34, and by that means materials may be delivered to the wormsupporting tube l1 and be carried by the worm therein to the left and bedischarged directly into the combustion chamber 2. The action of theworm blade 32 will thoroughly mix any materials which are passed throughthe tube H by means of the revolutions of the worm.

On the inside of the tube l5 and on the outside of the worm tube I1there is fixed a mixing block 31 which on its outside there is arecessed space 38 encircling the interior of the tube l5. This mixingblock 31 is, as it were. a ring and lengthwise through this ring and onthe inside of the ring, which contacts the tube ll, there is a series oflongitudinal holes 39 extending through the whole length of the block31. The space 38 is connected to the holes 39 by means of perforations40 at intervals along the length of the series of holes 39.

On the outside and lower side of the tube l5:

there is mounted a vertical tube 4| which'is open to a chamber 42 whichencircles the tube l 'l on the inside of the tube i5. This chamber 42 isopen through the series of longitudinal holes 39.

At the left of the tube 4| there is mounted a vertical pipe 43. Thisenters the inside of the tube l5 opening into the recessed' spaoe 38 andthus fluid materials may enter by the pipe '4! and pass through theholes 39 into the recessed space 38 and then cut the pipe, 43 or areverse motion of the fluid may enter pipe 43 and pass around to go outof pipe 4|, but therealpup.

4 pose of this construction is to provide the means whereby what will beentered to the inside of the tube l5 through the pipes 4| and 43 will bemixed together and pass out through the holes 39 into the chamber 44which surrounds the tube l1 on the inside of the tube |5 at the left endthereof. Inside of this chamber 44 there is a coil 45 simulating a coilspring, but in fact is only a worm, the purpose of whichis to cause thematerial discharged from the holes'39 in the block 31 to move in aspiral manner around the tube and in the inside of the tube l5 andthereby the materials will become thoroughly mixed as they aredischarged into the combustion chamber 2 as it passes through'betweenthe spoke ring I9.

This construction as described in relation to the tube barrel l5 and itsmounting provides means whereby materials may enter to the combustionchamber 2 from the pipe 3| and the pipes 4| and 43 and the hopper 34simultaneously. The materials which enter to the combustion chamber 2through thepipes 3| and 43 and the hopper 34 will become thoroughlymixed. What passes through the pipe 3| through the worm shaft 2| willact as desired as a blast drawing into the combustion chamber 2 what isdelivered by the worm blade 22 and the pipes 4| and 43. Thus the pipe 3|may supply steam, air, gasor fluid burning oil. This will also be trueof what may be supplied to the combustion chamber 2 through the pipes 4|and 43.

What is supplied through the medium of the hopper 34 may be granular ormore or less liquid in form as desired and be thoroughly mixed duringits movement to Where it is discharged within the combustion chamber 2.

By this construction and arrangement, ore or metallic material of anysort, together with fluxing material and carbonaceous or other materialmay be so proportioned that when it enters the combustion chamber 2, thetemperature will be at such a high degree as to flux and smelt the saidmaterial instantaneously, causing the metallic elements to drop downinto the lower region of the chamber 3 and accumulate in the catch basinid of the bottom of the chamber 3. Meantime the hot gases which arebeing released by the fusing and the smelting reactions will be car--ried out through the tube 5 and through the pipe 8 to the cooling andcondensing means which normally will be provided with cooling capacitywhich is expected to be sufficiently rapid to auto-s matically flow outof the pipe 5, as is indicated by the arrows shown on the drawings inFigure 1.

The alternating construction as shown by Figure 3, is to indicate thatmyjnvention is not limited to the use of a single volume settlementchamber, but those chambers may be duplicated in repetition to as manyas may be needed in any given installation for any special purpose.v

In Figure A indicates a primary or first chamber to be entered by thedischarge from any combustion chamber 2 and B indicates a supplementalchamber connected to the chamber A by the inclined pipe (3. At thebottom of each of given installation, there will be provided catchbasins D for each chamber. In this manner there will occur avariation'in the character of the material deposits'from chamber tochamber as the settlementbf. the lighter product. naturally will occurlater as compared to the heavier deposits that willtake place inthechamber first to be entered.

I have used the descriptive words combustion chamber as the chamber inwhich the final chemical reactions take place on the materials whichhave been previously prepared, mixed and moved into the said combustionchamber. Not every chemical reaction which will take place in the use ofmy apparatus may be considered a combustion, and as I have used the word"comlbustion, it must be interpreted to cover any re actions which takeplace in a chamber of that class as relates to the materials to whichare passed through the mechanisms which discharge those materials intowhat I have called a combustion chamber.

Many of the services for which my mechanisms provide the means forcarrying out, are what are understood as deoxidizing, but I also usethis apparatus for'oxidizing materials and have provided, as hereinshown and described, means for not only deoxidizing but also foroxidizing materials which have been entered into the so calledcombustion chamber by means of my mechanisms.

My mechanisms provide for handling gaseous, liquid and granularmaterials. These mechanisms may also be used entirely with liquid andgaseous materials which will react in mixing together when passedthrough my mechanisms into the reaction chamber, which I have hereingenerally described as a combustion chamber.

What I claim is:

1. In an apparatus of the class described, a body supporting tube, saidtube open at one end and connected to a combustion chamber, the

other end of said body tube closed providing a circular chamber on thisclosed end, a worm supporting tube mounted within the said body tube andpassing entirely through the said body tube, amixing block mountedwithin the said body tube and over the said worm supporting tulbe, saidmixing block provided with openings entering the said circular chamberof the said body tube and extending through the said mixing block, anentrance pipe into the said circular chamber of the said body tube, aring shaped opening around the outside of the said mixing block and onthe inside of the said body tube, a spiral coil for mixing purposeslocated on the inside of said body tube and on the outside of said Wormsupporting tube, an entrance pipe entering the said ring shaped openingof the said mixing block, and the said mixing block provided withopenings entering to the apertures through the said mixing block and tothe said circular chamber.

2. In an apparatus of the character referred to, the combination of: acombustion chamber, a cylindrical body opening in said combustionchamber, means for supplying a combustible material to said body toprovide a ring of heat at the open end of said body, a tube within saidbody opening in said combustion chamber, means to supply material to betreated to said tube, means to move the material in said tube toward theopen end thereof, and means to inject the material so fed into the ringof heat, and means in said combustion chamber for supplying a ring ofair around said ring of heat.
